N reflects available data at first, at-home, unsupervised assessment; Data for AD dementia patients was removed (N = 3 completed an at-home assessment 1–14 days post the in-clinic baseline); p-values from independent samples t-tests; In-clinic data is for the baseline and at-home data is for the first follow-up, 1–14 days later.
